|

|

In analog mode, data is shifted out as eleven nybbles:
|
||||
|
||||
_ ____________________________________________
|
||||
Req \_________/
|
||||
____ __ __ __ __ __ __ __ __

|

D XXX____X_____X_____X_____X_____X_____X_____X_____X_____X
|
||||
|
||||
The falling edge on Req causes data output to start. The host
|
||||
can't control the speed, it just polls the L/H and Ack lines to
|
||||
know when the data is ready to read.
|
||||
|
||||
Step D0 D1 D2 D3
|
||||
1 Select Start B' A'

|
||||
|
||||
In digital mode, Req is a simple multiplexer input:
|
||||
|
||||
Req 0 1
|
||||
D0 Up Throttle Up
|
||||
D1 Down Throttle Down
|
||||
D2 Left C
|
||||
D3 Right D
|
||||
L/H A E1
|
||||
Ack B E2
|
||||
|
||||
Start appears as simultaneous Left/Right
|
||||
Select appears as simultaneous Up/Down
|
||||
|
||||
This mode is almost compatible with a 6-button Towns Pad (on a
|
||||
real 6-button Towns Pad, buttons A and B can be read in either
|
||||
state, they bypass the multiplexer).
|
||||
|
||||
TODO:
|
||||
* Measure timings.
|
||||
* Confirm reported value for unused analog channel 4.
|
||||
* Confirm A', B', E1 and E2 bit mappings in analog mode.
|
||||
* Confirm buttons mapping in digital mode.
|
||||
- Is the mapping different in PC vs MD mode?
|
||||
* Implement trigger A/B rapid fire switches.
|
||||
* Implement channel shift switch (Y->X, X->Z, Z->X).
|
||||
* Implement special modes (holding buttons on power-on):
|
||||
- Double displacement modes:
|
||||
+ X/Y (hold SELECT + A')
|
||||
+ Z (hold SELECT + B')
|
||||
+ X/Y/Z (hold SELECT + A' + B')
|
||||
- Up/down reverse mode (hold C)

|
||||
|
||||
In analog mode, data is shifted out as eleven nybbles:
|
||||
|
||||
_ ____________________________________________
|
||||
Req \_________/
|
||||
____ __ __ __ __ __ __ __ __
|
||||
Ack \__/ \__/ \__/ \__/ \__/ \__/ \__/ \__/ \__/

|
||||
____ _____ _____ _____ _____ _____ _____ _____ _____
|
||||
D XXX____X_____X_____X_____X_____X_____X_____X_____X_____X
|
||||
|
||||
The falling edge on Req causes data output to start. The host
|
||||
can't control the speed, it just polls the L/H and Ack lines to
|
||||
know when the data is ready to read.
|
||||
|
||||

|
||||
|
||||
In MD mode, each pair of nybbles is transmitted in reverse
|
||||
order.
|
||||
|
||||
In digital mode, Req is a simple multiplexer input:
|
||||
|
||||
Req 0 1
|
||||
D0 Up Throttle Up
|
||||
D1 Down Throttle Down
|
||||
D2 Left C
|
||||
D3 Right D
|
||||
L/H A/A' E1
|
||||
Ack B/B' E2
|
||||
|
||||
Start appears as simultaneous Left/Right
|
||||
Select appears as simultaneous Up/Down
|
||||
|
||||
This mode is almost compatible with a 6-button Towns Pad (on a
|
||||
real 6-button Towns Pad, buttons A and B can be read in either
|
||||
state, they bypass the multiplexer).
|
||||
|
||||
TODO:
|
||||
* Dump MB88513 microcontroller from original controller.
|
||||
* Measure timings.
|
||||
* Latch data at beginning of packet.
|
||||
* Confirm A', B', E1 and E2 bit mappings in analog mode.
|
||||
* Confirm buttons mapping in digital mode.
|
||||
- Is the mapping different in PC vs MD mode?
|
||||
* Implement trigger A/B rapid fire switches.
|
||||
* Implement channel shift switch (Y->X, X->Z, Z->X).
|
||||
* Implement special modes (holding buttons on power-on):
|
||||
- Double displacement modes:
|
||||
+ X/Y (hold SELECT + A')
|
||||
+ Z (hold SELECT + B')
|
||||
+ X/Y/Z (hold SELECT + A' + B')
|
||||
- Up/down reverse mode (hold C)
|
||||
* Implement desktop (XE-1AJ/CZ-8NJ2) version:
|
||||
- Four analog channels
|
||||
- E1/E2 on a rocker switch (can't press simultaneously)
|
||||
- Hold mode for A and B triggers
|
||||
- Variable rapid fire rate for A and B triggers
|
||||
- Reset button
|
||||
- Different special modes
|
||||
- No Mega Drive mode
|
||||
- Start and Select not reported in digital mode
